1. To survive fresh water, the fish need a range of physiological adaptations . 2. Long-term endurance training induces many physiological adaptations both centrally and peripherally mediated. 3. In addition to behavioral adaptations, physiological adaptations help ectotherms regulate temperature. 4. Contrast effects are common in many perceptual modalities, and are similar to physiological adaptation . 5. Many physiological adaptations have evolved that make flight more efficient. 6. A number of physiological adaptations serve to prevent cavitation and to recover from it. 7. Numerous physiological adaptations aid the lifestyle of the short-beaked echidna. 8. Analyses such as these demonstrate the physiological adaptations to environmental changes that animals undergo. 9. Therefore, the effects of flight duration on physiological adaptation and readaptation could be examined. 10. Thorold's deer has a number of physical and physiological adaptations to its high altitude environment.
